Obsessive compulsive texting disorder (O.C.T.D.)

You text so much your thumbs are tired and your phone is your only friend.

I texted my mom 20 times about my day. My thumbs are sore and my phone is my only friend.

I'm texting you because I have nothing else to do and my phone won't stop me.

I texted my friend 15 times. My thumbs are dead. My phone is alive.
